ObjectiveTo evaluate the clinical value of capsule endoscopy (CE) image screening system developed by our group.MethodsBetween March 2011 and June 2011,50 patients (29 males and 21 females with a mean age of 45.7(45.7 ± 4.1 ) ) underwent CE in our department.CE images were reviewed,and processed by the screening system at the rate of 50％,60％,70％,80％ and 90％,respectively.After reviewing the remaining and the deleted frames,the endoscopists calculated the remaining rate of the lesions by recording the number of lesions of all patients and the number of remaining lesions.The procedure time and the total number of the frames of each case were also recorded.ResultsA total of 39 patients of 50 had lesions and the detection rate was 78％.91 lesions were detected in the 39 patients,most of whom had more than 2 lesions.When the prescribed deletion rate was less than or equal to 60％,the lesion remaining rate reached 100％,with a mean frames of the cases of 46 242,and the mean processing time of 15.62 min.ConclusionWith all the lesions remained,the system can delete 60％ similar frames in a very short time,which greatly reduces the diagnosis time and workload for endoscopist,and improves the efficiency of capsule endoscopy.
